PERTH STATISTICAL DIVISION
The Perth SD experienced the state's largest population growth, increasing by 52,200 people (3.2%) in 2008-09. The Perth SD accounted for 77% of WA's growth between June 2008 and June 2009, and was home to 74% of the state's population in June 2009.
The largest population growth continued to occur in the outer suburban fringes of the Perth SD. Wanneroo (C), Stirling (C), Swan (C), Rockingham (C), Cockburn (C) and Gosnells (C) each grew by more than 3,000 people in the year to June 2009. Together, these LGAs accounted for over half of the growth in the metropolitan area. Wanneroo (C) and Stirling (C) are in the north, Swan (C) is to the east, Gosnells (C) to the south-east and Rockingham (C) and Cockburn (C) are coastal LGAs to the south of the city.
In the Perth SD, the fastest-growing LGAs in 2008-09 were Perth (C) (up by 12.8%), Serpentine-Jarrahdale (S) (7.6%) and Wanneroo (C) (7.1%).
No LGAs in the Perth SD experienced population decline in the year to June 2009.
The growth in southern suburban Melville (C) and in southern coastal Rockingham (C) took each of these centre's populations past the milestone on 100,000 people in 2008-09.
POPULATION CHANGE IN THE REGIONS
At June 2009, the population of the remainder of WA was 586,100 (26% of the state's total). This population had increased by 15,900 people (2.8%) since June 2008.
All eight Statistical Divisions within the remainder of the state grew in population in the year to June 2009.
South West SD grew the most, increasing by 4.0% (9,500 people) in 2008-09. Nearly all LGAs in South West experienced growth during the year with Murray (S) growing the fastest (6.5%), and Mandurah (C) gaining the most people (3,300). Capel (S), Dardanup (S) and Busselton (S) also increased at a rate faster than the region's average.
Outside the metropolitan area, the Pilbara was the state's second fastest-growing SD, with 3.1% growth, followed by Lower Great Southern (2.2%), then Kimberley (2.1%).
Although not apparent at the broader (SD) level, almost one-third of LGAs outside the Perth metropolitan area declined or had no change in their populations during the year to 2009. Of these, over half already had populations below 1,000 people.
WA's population density at June 2009 was 0.9 people per square kilometre (sq km). Most of WA had a very low population density, with over half of SLAs (comprising 97% of the total area of the state) having less than one person per sq km. The population density of the Perth SD for the same period was 310 people per sq km, lower than Australian capital cities combined (370 people per sq km).
At June 2009, the SLAs with the highest population densities within the Perth SD were Vincent (T) (2,700 people per sq km), Subiaco (C) (also 2,700) and East Fremantle (T) (2,400).
With a density of just 18.2 people per sq km, Serpentine-Jarrahdale (S) in the south-east had the lowest density of all SLAs within the Perth SD, followed by Mundaring (S) (59.5) in the east.
Between June 2008 and June 2009, the largest increases in population density within the Perth SD occurred in the SLAs of Perth (C) - Remainder (up 170 people per sq km), Perth (C) - Inner (110) and Subiaco (C) (70).
CENTRE OF POPULATION
At June 2009, the centre of population for WA was in the Avon Valley National Park, in the LGA of Toodyay (S). In the five years to June 2009, the centre moved approximately 3.3 kilometres south-west, reflecting strong population growth in Perth.
The centre of population for the Perth SD at June 2009 was in the Swan River, between the Perth central business district and South Perth.
